Abstract: 1390857 Making composite powder INTERNATIONAL NICKEL Ltd 6 July 1972 [6 July 1971] 31572/72 Heading B3A [Also in Division C7] A process for producing a composite powder of an aluminium or aluminium-base alloy matrix containing a dispersion of alumina comprises mechanically alloying the constituents by milling a powder charge comprising aluminium or aluminium oxide coated aluminium particles in the presence of an asymmetric organic surfactive agent in vapour or liquid form and in an amount less than 4% of the total powder charge by weight to produce uniformly dispersed, substantially equiaxed particles of aluminium oxide not exceeding 2000 in diameter in the aluminium or aluminium alloy matrix. Preferably, 0À3 to 2% by weight of a surfactive agent is used and the agent ideally has a boiling point not exceeding 200 C., contains from 1-5 carbon atoms per molecule and the molecules each have a metallophilic and a metallophobic group. The agents may consist of organic acids, alcohols, ketones, aldehydes or ethers. The agents can be distributed directly to the mill with the powder charge and grinding media before milling or periodically. Alternatively, they can be vaporized and continuously or intermittently introduced in vapour form to the mill during milling. The aluminium oxide is provided by layers on the aluminium particles during the milling and oxygen can also be added to the mill along with fine aluminium oxide powder. The grinding ball to powder volume ratio is from 4 : 1 to 50 : 1, preferably 15 : 1 to 30 : 1, and ball, attritor, shaker, vibratory and planetary ball mills can be used. The initial powder charge can be in the form of pre-alloyed particles of the desired alloy or of different powders of the respective alloy constituents. The alloys can contain by weight one or more of the following elements to the amounts indicated: 2% Ni, 0À5% Cr, 10% Cu, 21% Si, 1À5% Mn, 10% Zn, 10% Mg, 20% Sn, 2% Fe, 1% Pb, 1% Bi, 0À2% Zr, 0À2% Ti, 1À5% Li, 0À1% V, 0À8% Cd, 0À02% B, 0À05% Be. Refractory oxides of metals other than aluminium, e.g. yttria, thoria and magnesia, suitable for dispersion strengthening can also be added to the powder charge. The mechanically-alloyed composite powders can be consolidated into powder metallurgy products by mechanical or hydrostatic compaction and sintering and hot extrusion, by hot pressing and hot extrusion, by hot extrusion or hot rolling without prior compaction or sintering. If the products are to be cold-worked, e.g. drawn into wire, rolled into sheet, the C content should be #0À5%, although higher contents can be tolerated with hotworking.
